Flames ripped through the interior of a Beatty Street home in Medford on Tuesday, drawing multiple fire engines from Medford Fire-Rescue and temporarily closing the street.

The blaze was reported by neighbors at noon at a home in the street's 200 block. Fire officials said five engines and about 17 firefighters responded to the scene.

"There was light smoke from the structure coming out from several areas," said Medford Fire battalion chief Ken Goodson. "The building itself was full of smoke."

Goodson described the home as an old structure that had been remodeled and added onto many times. That, plus the amount of smoke inside, made it difficult to track the fire's source.

"It took us about 10 minutes to get in there and find exactly where the fire was," Goodson said, adding firefighters found the flames in the back of the structure in one of the rooms. "We had to ventilate some of the smoke just to see it. It was so smoky."

Fire crews had the blaze under control in about five minutes but remained on the scene afterward to make sure spot fires did not reignite.

Police closed off all traffic on the street while crews battled the flames. Neighbors evacuated a nearby apartment complex as a precaution, fire officials said.

One person was reported to be home at the time but made it out unhurt. Two dogs and a cat also survived, Medford Fire Deputy Chief Gordon Sletmoe said.

Crews contained the flames mostly to the interior, but some did spread to a tree in the back of the home. A room and the side of the building received the brunt of the damage, though cost estimates were not available.

The incident remains under investigation. The cause is not yet known, but Goodson said it did not appear to be suspicious in nature.
